Need Help with Arrow Flight SQL

[de-sh]

Hi there, been experimenting with using apache arrow flight for remote SQL execution, and started running into the following issue, would be really helpful if someone could point out what I am doing wrong! 😅

My code:

1. server.rs
2. client.rs

Ipc error: Status { code: InvalidArgument, message: "DecodeError { description: \"invalid wire type value: 7\", stack: [] }", metadata: MetadataMap { headers: {"content-type": "application/grpc", "date": "Mon, 14 Jul 2025 05:34:07 GMT", "content-length": "0"} }, source: None }
Error: IpcError("Status { code: InvalidArgument, message: \"DecodeError { description: \\\"invalid wire type value: 7\\\", stack: [] }\", metadata: MetadataMap { headers: {\"content-type\": \"application/grpc\", \"date\": \"Mon, 14 Jul 2025 05:34:07 GMT\", \"content-length\": \"0\"} }, source: None }")

Thanks and regards
